AI Generated Solution

To solve the problem, we need to determine the time it takes for a radar signal to travel to an airplane 300 km away and back. Here’s the step-by-step solution: ### Step 1: Understand the Problem The radar sends a signal to an airplane that is 300 km away. The signal travels to the airplane and then reflects back to the radar. We need to find the total time taken for this round trip. ### Step 2: Identify the Given Values - Distance to the airplane (d) = 300 km - Speed of the signal (v) = \(3 \times 10^8\) m/s ...
